Christmas-bells
Christmas bells (Blandfordia nobilis) is a perennial monocot in the family Blandfordiaceae, native to heathlands and scrublands along the coast and tablelands of New South Wales, Australia. It is one of the smaller-flowered species within the genus Blandfordia and occurs in similar habitats to its congener Blandfordia grandiflora, though with a somewhat different distribution pattern. Like other members of the genus, Blandfordia nobilis produces tubular, bell-shaped flowers in combinations of red, orange, and yellow, on stems arising from basal tufts of tough, linear leaves. The flowers appear in the austral summer, coinciding with the Christmas holiday period. The species grows in seasonally wet, nutrient-poor sandy soils in coastal heath and woodland communities, and is considered fire-adapted, with flowering and regeneration often enhanced after disturbance. Christmas bells are emblematic of the New South Wales coastal landscape and have long been associated with summertime festivities in Australia. The species faces pressures from habitat clearance, urban development, and altered fire regimes. Its flowers are attractive to nectar-feeding birds and insects. All Blandfordia species are protected from collection in the wild under state legislation.
